ELECTRICeFAN SCREEN AND GUARD.

speeincation of Letters' Patent.

Application filed. March 18, 1914, Sierial No. 825,538.

To all whom t may concern Be it known that I, BENJAMIN F. Fnrr'rs, a citizen of the United States, and a resident of Chattanooga, in the county of Hamilton and State of Tennessee, have invented a new and Improved Electric-Fan Screen and Guard, of which the following is a full, clear, and exact description.

My invention has for its object t'o provide.

a screen which may be readily attached to an electric fan and which will guard the rear as well as the front and sides ofthev fan.

The screen is preferably constructed with a front memberhaving rearwardly extending portions sothat the front member will guard not only tlie front of the fan but also the sides of-the fan. The rear of the screen which is detachably secured to the extending portions otthe front screen member 'maybe permanently secui'ed to the fan motor casing -or if desired, this rear screen member 4may be constructed in sections which are hinged together and which may be disposed around the fan for guarding the rear ofthe fan when the rear screen member is secured to the rearwardly'extending portions of the front screen member.

, Additional objects 'of the invention will appear inV the following specification in which the preferred form of my invention is disclosed In the drawings similar reference charactersv refer to similar parts in all the views in whichj Figure 1 is a sectional elevation of thescreen showing the parts in section; Fig. 2

is a sectional elevation of the screen showing one. form of the rear screen member; Fig. 3 is a fragmentary view showing another form of the rear screen member; and Fig. 4 is a modified formof the invention showing the front screen member with a rounded lportion for extending over the front ofthe fan.

By referring to the drawings it will be seen that thefront screen member 5 shown in Fig. 1, has front portions 6 and 'rearwardlyextending side portions 7, the front portions G'being provided for guarding the front of the fan. 8 and the rearwardly extending side portions?Y being provided for guarding the sides of the said fan 8. rIhe vsaid rearwardly extending side portions 7 of the front screen member 5 are preferably Y connected with the' front portions 6 by .an

Patentea oct. 2o, 1914.

lated at 11 to the section 11 so that the sections 10 and 11 may be moved away 'from` eachother to permitl the said sections to be 15, the rear screen member formed of the sections 10 and 11, when in normal position, having a 'central opening 16 in which the fan shaft 15 is disposed. When the said rear screen member, formed of the sections 10 and 11 is disposed around the fan shaft 15,

the rims of the sections 10 and 11 are en.

gaged bv the termina-ls 1I of the spi-in 5 hooks 18 whichare mounted on the frame 9. In many cases the screen will be mounted on the fan when it is sbld and when the screen is to be used in this wav, I prefer to ilse the rear screen member 19 which is secured to the front screen member 5 in the same manner as is the rear screen formed of' the sections 10 and 11, but this Arear screen member 19 has inwardly extending arms 20 which project inwardly beyond the circular rim 21 which is disposed around the fan shaft 15. Theinwardly extending portions 22 of the arms 20 have orifices 23 in which may be disposed screws for meshing in threaded orifices n the -fan motor casing.

f -In Fig. 4 I show another yform 5 of a front screen member, this front screen member 5a ha'vingrearwardly extending sides 7a: Having thus described, my in vention' I claim as ,new and desire to secure by Letters. Patent: Y
